Specification of Letters Patent.

Patented Aug. 25, 1908.

Application filed March 19, 1908. Serial No. 422,073.

To all whom it may concern:

Be it'known that I, GEORGE W. DOVER, a

1 citizen of the United States, residing at Cranston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Pins, of which the following is a specification.

My invention relates to pins, but more particularly to what are commonly known as cuff pins, and has for its objects the ends commonly sou ht by such structures, but more particular y to increase the strength of the article and prevent the cramping of the pliln pivot, and facilitate the introduction of t e cheapen, and strengthen the tongue head, and to prevent distension of the journal cars by the tongue head.

To the above ends essentially my invention consist-s in the novel construction and combination of parts hereinafter set forth and claimed.

In the drawings which constitute a part of my invention, Figure 1 is a plan view of the original planchet. Fi 2, a like vieW of the samewith the margina projections upturned. Fig. 3, a side elevation of the same. Fi s. 4 and 5, side and top plan views respective y of the entire pin. Figs. 6 and 7, sections on lines a; w and y y respectively of Fig.4, and Fig. 8 a plan of the blank from which. the tongue head is formed.

Like reference characters indicate like parts throughout the views.

My pin is constructed as follows:

A blank or planchet A, nearly elliptical in general outline, is cut from a thin sheetof metal.

form a catch. By virtue of the incisions, D Y

and F, it will be noted that the ears, B and E, rise from points in from the margin of the blank or plate, A; leaving marginal cavities or spaces, G G in the plate adjacent the ears,

atter into the ears; also to simplify,

Near one end of the blank are oppo- 1 sitely disposed lateral lu s, B B each pro- The margins of B, and a marginal cavity, I-I, adjacent the catch, E, The base plate, A, is secured in an oblong cupped front plate, I, by rolling the margin, J, of the latter over the margin of the plate, A, at every point.

'K represents a pin shaft, the head of which is formed from a blank, L, shown in Fig. 8, having equidistant from its center perforations, 0. This blank is folded over the blunt end of the shaft, K, and itssides, 1, brought together so that the openings, C, coincide.

Through these openings, C, a pintle, M, is

driven, thus frictionally holding the ears or sides, 1, tight together so that the shaft, K, will not loosen, nor the ears, 1, spread-or press outwardly against the outer ears, B, of the joint or setting. The pintle, M, is then placed in the openin s, C, and the walls, B, pinched into vertica position as shown in It will be observed that the flange, roll, or bead, J, by virtue of its remoteness from the margin of the catch and cars, is continuous around the entire margin of the base plate, A, whereby the'plates are strongly united,

and no raw ed es or irregularities are presented to offen .the eye or cut or catch the adjacent fabric. r Furthermore, the 'positioning' of the ears,-B in from the plate margin enables the latter when upturned to have their sidefaces in true fparallelism, whereby the pintle is insured 0 easy insertion, and cramping of the pin tongue head between the ears avoided, as would be the case if the ears rose'from the mar in-of the plate, in which case the surfaces 0 the ears would be angularjzfinclined with relation to each other.

at I claim is,

1. In a pin of the type set forth, the combination with a base plate of journal ears cut inwardly from the margin of the plate and.

flange upon the front plate overlapping the entire margin of thebase plate.

2. In a pin of the type set forth, the combination with'a base plate, .of journal ears upon the plate, a'catch member cut inwardly from the margin of the plate and parallel with the ears, a front late, and a flange upon the front late engaging the entire margin of the base p ate.

3, In a pin of the ti pe set forth, the cominner facesv and rovided with openings, and bination with a base p ate, of 'ournal ears cut a pintle tightly eld in the openings to preinwardly from the margin oi the plate and vent distention of the ears. parallel with each other, a catch member In testimony whereof I have afiixed my 5 upon the plate, a front plate, and a flange signature inpresence of two Witnesses.
